Well starcraft has sold. Now the shopping begins, I'm pretty sure I've settled on the 17.56-2 expanda. Hubby hates the pop top and combo shower toilet, trying to convince him pop tops aren't as much trouble as he's making out and we can still use the shower in the combo just fine! He wants the 21.64-1 expanda but I don't want to spend that sort of money lol
If you are going for the expanda the poptop is going to be least of his worries, having canvas bed ends.
Realise you have come from a Starcraft with solid walls all round. I have the Discovery with bunks.
My decision for this was I wanted those hard walls around me so in in extreme windy wet weather there was nothing to worry about. Also wanted the least set up. As far as the bunk bed being needed to be setup put down I taught the kids how to do that so in the morning I just sit in bed and watch them.
Again it all depends how you use the van. If your planning to do week long trips in one spot the extra time to set up bed ends and covers might not be an issue. My intended use was for shorter weekend trips and to allow stops on the road at night.
Also with expanda make sure the fridge is not on the door side if you want a full annex. Good luck with the decision.
